fddd390d31 on the C64, if not using floats, disable basic ROM in startup to gain another 8Kb of RAM
MEMTOP is adjusted to $d000. This gives us 50 Kb of contiguous program RAM space. ($0801-$CFFF)

85e87dfe2e consolidate @rombank and @rambank into just @bank 2024-11-03 21:15:11 +01:00
Irmen de Jong
155896c4c7 added @rombank and @rambank bank number tags on romsubs
on cx16 and c128 targets the compiler then automatically inserts a CALLFAR instead of a regular JSR to automatically do the bank switching.

a6159702da defers are now only registered/called when flow of control actually reached the defer statement
a defer statement sets its corresponding bit in a bitmask that is shifted in the defer handler routine to see what defer blocks to call.

9851d14fb9 added if expression: ubyte a = if b>0 44 else 55
it doesn't generate the best code yet, like regular ifs do.

38ef394e15 IR codegen: global vars with numeric initialization value are now also put into the VARIABLESWITHINIT section rather than requiring explicit code instructions to initialize them in INITGLOBALS.
Note that something similar, such as putting those variables inline in the program initialized with their value and all, cannot be done for the 6502 codegen: the program needs a mechanism to reset ALL variables when it runs a second time.

e9edffa9f0 remove support for array-to-array assignments (other than initialization of variable declaration)
Just use an explicit sys.memcopy(src, dest, sizeof(dest))  or assign array members individually.
